Pull out method success

I've seen a lot of women post about the pull out method on here. I'm just curious bc I've used it (solely) on and off for nearly 8 years and never gotten pregnant (only while in committed serious relationships). I've never had an STI, get tested regularly. And I did get pregnant at 17 but ended terminating bc I was too young. Spare me the judgement or lectures, I'm a grown woman, and just curious is other had success, without fertility issues later in life.
